HI, I currently have a Invidia dual exhaust with a custom hi-flow cat, I was wondering whats a good header/extractor that works the best with the invidia?

what will give me the most gains and will i need some sort of tune? even tho i don't have a computer.

cheers.

damn should of got this instead of my invidia lol

 

headers performance isn't dependent on the exhaust, it's dependent on the head and cams.

 

So what do you think of First header going into a invidia dual?

 

j's and toda seem to be the ones that will make the most power, also for you since you have an ap1, i have read that if you get the ap2 mugen header it makes power as well.
